ln tho l'orin shown in "ij,1'::. l und 5 tlm-IWW' IOS a pipe 15, with preferably one end closed and having a series 'of lateral openings 16, may be arranged at any point above the trough and attached, by means of a `section of hose or other piping, to a suitable supply of water, so that the material as it passcs under the pipe `1.5 may bc sprayed or sprinkled to the desired extent.

ln operation the several substances are placed in their respective hoppers of the propoitioning-machine of my device by which they are accurately measured and discharged into the trough, where the plows 4 carry them slowly forward, at the'same time rolling the material overand over and moving it from side to side of the trough, where it passes under the pipe 15. It may have the desired amount of Water added, the mixing process continuing until the material is discharged from the upper end of the trough into the hopper 14, from which it may be drawn as re uired, 0r directly upon the foundation or ot ier point where itis to be used, as the material when it leaves the upper end of the trough should be iii just the correct condition for tamping into place.

It vv ill be observed that the top of the receivin -hoppers may be arranged close to the groun or working-level, so that the materials may be readily dumped into them from wheelbarrows or other means of transportation or shoveled or otherwise thrown into them by the expenditure of the least amount of labor and time. The discharge end of the mixer, however, may be at a considerableA elevation, so that the mixture may be received into wheelbarrows, carts, or other receivers, or, if desired, any of the wellknown means may be employed, so that the material may be distributed over a considerable surface without rehandling.

Having thus described my improvement, it is obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention. Hence I do not/Wish to be understood aslimiting myself to the exact forni or construction shown.

What I claim as new, and desire to secure by Letters Patent, is-

1. A device ofthe kind described, comprising a trough, in combination with a plurality of plows extending from alternate sides thereof toward the op osite side, and inclined backward from the bottom and adjacent sides of the trough, means for moving said plows longitudinally o said trough, and means for directing material into said trough.

2. 4A device of the kind described, comprising an endless movable carrier provided with a plurality of lows alternately proiecting from its o posite sides, the operating surfaces of eac i plow being formed to present an inclined surface to the materials operated upon whereby said material will tend to move toward said carrier, and means for supporting and driving said carrier, in combination with a trough in which said lows are arranged to operate, and means or directing materials into said trough.

3. A device of the kind described, comprising a trough, and carrying means arranged to move longitudinally of the trough, in colnbinatidn with a series of plows operated by said carrying means, alternately extending from thc edges toward the o posite side ol said trough and inclined bac ward from the adjacent side thereof toward the center, and means for directing material into said trough.

4. A device of the kind described, comprising a trough, and carrying means arranged to move longitudinally of said trough, in combination with a series of ploivs operated by said carrying means, alternately extending from each side of said trough toward the o posite side, and inclined backward from the iiottcm toward the top of said trough and means for directing material into said trough.

.5. A device of the kind described, comprising a trough, a series of plows positioned within said trough extending alternately from the sides thereof toward the opposite side, and inclined backward from the sides and bottom toward the center and top of said trough, means for moving said ploWs lon itudinaliy of said trough, and means for (irecting material into said trough.

6. A device ofthe kind described, comprising an endless mo able carrier provided with a plurality of plows alternately pro'ecting from its opposite sides the face of eac plow being inclined forward from said carrier, and means for supporting and driving said car- IOC rier, in combination with an inclined trough,

in which said plows are arranged to operate, means for directing materials into said trough, and means for spraying a liquid onto the materials passing through said trough.

7. A device of the kind described, comprising an endless movable carrier provided with a plurality of plows projecting alternately from its o posite sides the face of each plow being inclined forward from said carrier, and means for guidin and driving said carrier, in combination wit a trough in which said plows are arranged to operate, and means foil simultaneously directing a plurality of ingredients into said trough.

8. A device of the kind described, comprising an endless movable carrier provided with a plurality of plows alternately projecting from its o posite sides the face of each plo iv being inclined forward from said carrier, and means for guiding and driving said carrier, in combination with a trough in which said carriers are arranged to operate, means for simultaneously directing a plurality of ingredients into said trough, and means for spraying a liquid onto the materials passing t rough said troug lso Corrections in Letters Patent No.283l,658.
